...Karen J. MURCHIE; Garry L. JENNINGS; Bronwyn A. KINGWELL Despite providing symptomatic relief in patients with congestive heart failure (CHF), supplemental oxygen (O 2 ) has been demonstrated to increase total peripheral resistance. The present study investigated the possibility that O 2 inhalation...

The present study examines these parameters during coronary artery bypass surgery. We used...

...I. M. Petyaev; A. Vuylsteke; D. W. Bethune; J. V. Hunt 1. Although not often appreciated, it is a fact that molecular oxygen is more soluble in lipids than in aqueous solution. We have recently developed a method to monitor oxygen within the lipid content of plasma. Monitoring plasma oxygen is one...
